Need PSU Wattage Reccomendation

[EM3]

I'm not exactly sure what would be needed since this computer will be running two video cards, not in sli/crossfire, for a multi monitor set up (8). With that being said there will be two geforce gtx 750s that require 400w for one so I'm not certain how much two would require + all other components.

Here is everything the build will have aside the PSU.

My intial guess is 750~+ watts. There will not be any overclocking.

550 would be enough. the card itself only uses 60w. also you shouldn't do that. just buy a 4g 760 for the same price it would be twice as good.

What a surprise, I would have thought much more power would be needed than a 550w with everything combined and two video cards. Guess I'll be able to save a few dollars.

For a system using two GeForce GTX 750 graphics cards a minimum of a 450 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 28 Amps or greater is recommended.

The 450W version of that XFX is fine if you are not going to upgrade. But if you are going to upgrade in the future then get the 550W model. Anything up too a GTX 780 would run with that no problem.
